A Comparative Study of Viscosity Models in Nanofluid Flow Induced by Two Rotating Disks with Homogeneous-Heterogeneous Reaction

An analysis has been carried out to study of nanofluid flow induced by two stretchable rotating disks. Energy equation is established by taking heat generation/absorption and radiation effects into consideration. Besides these effects of homogeneous-heterogeneous chemical reactions are examined. The main purpose of this work is to determine the comparative study of viscosity models in nanofluids. We convert system of Navier-Stokes equations into system of ordinary differential equation after employing the similarity transformations. Impact of various involved parameters on velocity, temperature and nanoparticle volume fraction is tested. Azimuthal velocity components enhances for higher values of stretching parameter S-2. Temperature field decays for large values of Prandtl number. Nanoparticle volume fraction has decline for increasing values of homogeneous parameter and enhances for larger Reynolds number.
